THREAD-PARTING mnenamsm iron Looms.

Application filed m 15, 1912. Serial no. 709,348.

To all whom a: may concern;

Be it known that I, ALoNzo E. Rnoanns, a citizen of the United States, and resident of Hopedale,co unt-y of Worcester, State of Massachusetts, have invented an Improvement in Thread-Parting Mechanism for Looms, of. which the following description,

in connection with the accompanying drawing, is a specification,.like characters on the or spent filling being parted between the .15

drawing representing like parts.

This invention applies to looms of the type wherein the running filling is replenished prior to complete exhaustion, the old cloth and the shuttle by parting means usually mounted on a swinging support or the partin arm,'and which latter is generally arranged to perform the function of a shu-ttle-feeler; Ordinarily the engagement of the teeler with an improperly boxed shuttle will prevent of the spent fillin and it will also restram the operation ,of t e replenishing mechanism, butif the shuttle is so positionedthat its steel tip is engaged by the March 2, 1909 I show a loom structure in feeler the 'fillin will be caught and severed almost invariab y. When such severance occurs w'thout re lenishment, two empty picks wil be ma e in the cloth,"which is most objectionable. v

In my prior Patent No. 913,916 granted which the parting device is mounted on a swinging support or carrier of usual construction but which does not act as a shuttlefeeler, the shuttle-fteeier being pivoted on the lay to swing in a vertical path-toward and from the raceway adjacent the mouth of the replenishing box; 'This feeler is moved to feeling position by engagement with an actuating member on the'swinging support as-the latter moves rearward when replenishment is called for, and if the shuttie is boxed properly the'feeler movement is the shuttle-feeler and the support for the parting device are separate members and the feeling action of the former is etlected by or throiwh operative movement of the latter to position the parting device for operation. My present invention has for its object the production of improved-mechanism of the general character disclosed, and so constructed that the feeler is released automatically immediately after it has performed the feeling action, rovided the shuttle is boxed properly. I? the shuttle is boxed 'impro )erly the feeler is not released, and it Specification of Letters Patent. Patented NOYQZG, 1912.

acts t rough the swinging support to prevent not only the operation of the parting device but also the actuation of the replenishing mechanism. I The release ofthe feeler after it has performed its proper function removes it from the immediate vicinity of the shuttle, so that any accidental pinching .or catcht'n of the filling by the feeler is obviated t the shuttle is boxed improperly and is-engaged by the feeler the latter is arrested in its movement, and as the feeler isdisengaged by its actuating device simultaneously with the completion of its feeling stroke the arrested feeler will act to prevent I the com lete movement of the actuating device, herein shown as the support for the parting device. Consequently the said support' cannot contact with any part. of the shuttle. nor can the parting device he operated while the shuttle-feeler is. in engagement with the support, and the spent'filling endcannot he cut by the parting device or by being nipped between the supportand the shuttle.

In my present invention, l have mounted the feeler upon the lay to swing in a lateral path parallel to the raceway mto'and out of feeling position, a spring retracting the" dog which is engaged hy a' suitable hunter.

parting device, to efiect the fe mg action of the feeler when replenishment is called for, the dog yielding to permit the return movement of the hunter member after the replenishing action has been completed. I

The present mechanism has roved highly etlicientin actual practice, an the location and operation of the shuttle-feeler as herein set foal-h is most satisfactory.
